Collection: Catadioptric & Cassegrain Telescopes

Catadioptric telescopes, also known as compound telescopes, are a category of telescopes that combine both lenses (dioptrics) and mirrors (catoptrics) in their optical design. These telescopes utilize a combination of lenses and mirrors to achieve specific optical characteristics and to correct for optical aberrations, resulting in high-quality, versatile instruments for astronomy and other applications.

Common types of catadioptric telescopes include:

  • Schmidt-Cassegrain Telescopes (SCT): These telescopes feature a primary mirror that is spherical and a Schmidt corrector plate. The secondary mirror is usually positioned near the corrector plate, allowing for a compact and portable design.

  • Maksutov-Cassegrain Telescopes (Mak or MCT): Maksutov telescopes use a spherical meniscus-shaped corrector lens and a spherical primary mirror. They are known for their compact size and excellent image quality.

  • Ritchey-Chrétien Telescopes (RC): These telescopes use hyperbolic primary and secondary mirrors, often with no corrector plate. They are favored for their suitability in astrophotography and their ability to provide a wide, flat field of view.

Catadioptric telescopes are prized for their versatility, offering a balance between image quality, portability, and ease of use. They are commonly used in amateur astronomy, professional observatories, and various scientific applications where high-quality imaging and compact design are essential.
